[Windows] Add roaming option to user_data_dir() (for use on Windows only)
and change the default user_data_dir behaviour to use a non-roaming
profile dir (CSIDL_LOCAL_APPDATA instead of CSIDL_APPDATA). Why? Because
a large roaming profile can cause login speed issues. The “only syncs on
logout” behaviour can cause surprises in appdata info.

appdirs 1.0.1 (never released)

Started this changelog 27 July 2010. Before that this module originated in the
Komodo product as applib.py and then
as applib/location.py (used by
PyPM in ActivePython). This is basically a fork of
applib.py 1.0.1 and applib/location.py 1.0.1.
